Electrical terminals - Import export

Politubes produces various types of insulating Mylar, Nomex, Kapton, 2LSO, DMD tubes & insulator caps designed according to the requirements of hermetic closure, positioning, size and protection from chemical agents as required by our customers. They can be supplied in perfectly round or oval form to facilitate insertion and to reduce the overall dimensions. Their dielectric strength can reach 303kV/mm with reference to the ASTM-D-149-91 test method and are used within a temperature range of -50°C/+300°C. Our adhesives, carefully selected during our forty years of experience, comply with all REACH and RoHS regulations and guarantee that the original properties of the films used are fully maintained. They are used for insulation and thermal management in stator slot E-Motors, thermal protectors insulation inside electric motors, motor lead termination, compressors, in order to avoid wires ends to damage the surrounding parts

FR-4 is a composite material composed of woven fiberglass cloth with an epoxy resin binder that is flame resistant (self-extinguishing). With near zero water absorption, FR-4 is most commonly used as an electrical insulator possessing considerable mechanical strength. We carry out bushings, flanges, plates, manifolds, bolts, etc. Key Properties FR Grades are Fire Retardant High Dielectric Strength High Mechanical Strength Low CLTE Applications Arc Barriers Downhole Oil & Gas Components Electrical Housings Electrical Insulators Structural Components Terminal Boards
